AMD RADEON HD 6770M, FAST GRAPHICS CARD FOR PC OR LAPTOPS

AMD Radeon HD 6770M (sometimes also called ATI Mobility Radeon HD 6770 or similar) of the middle class is a fast graphics card for laptops. It supports DirectX 11, is the successor to the HD 5770, and has higher clock speed, 80 more shaders, and UVD3 Eyefinity + video decoder. However, it still occurs in 40 nm and based on the same chip as the 6700M and 6600M whole series whist.

The 480 Stream processors are still based on the "old" 5D architecture similar to the 5000 series. Therefore, the number of shaders is not comparable to the current 1D Nvidia GPU core. Tessellation performance should improve (like the desktop of the series 6800) with the new cards. The stream processors can be used with DirectX 11, OpenGL 4.1, 11 and OpenCL DirectCompute. With these last two nuclei can also be used for general calculations, such as video transcoding.

The 3D performance should be a bit better compared to the old Radeon HD because of the greater amount of shaders 5770 and higher clock speed. Therefore, current and demanding games should run fluently at 1366x768 and medium to high details. Less demanding games like The Sims 3 and FIFA 11 should run on high detail and resolutions.

The new UVD3 video decoder supports decoding MPEG-4 AVC/H.264, VC-1, MPEG-2, Flash, and now Multi-View Codec (MVC) and MPEG-4 Part 2 (DivX, Xvid) videos high definition graphics card. In addition, the series 6700M HD integrated HD audio controller for transmitting high-definition audio (TrueHD or DTS Master Audio) via HDMI and DisplayPort (eg videos f or Blu-Ray).

HD3D AMD processor technology with support for Blu-Ray 3D and 3D displays (integrated and external). However, the solution is not as mature as Nvidia 3D Vision. Thanks to the graphics chip can theoretically lead to Eyefinity 5 monitors simultaneously. However, this only works if the laptop has enough DisplayPort outputs.

The energy consumption of the chip should be similar to the Mobility Radeon HD 5770 and therefore suitable for 15 "laptops and more.
